Apple Retina Display (via Jonesblog)

So, if a normal human eye can discriminate two points separated by 1 arcminute/cycle at a distance of a foot, we should be able to discriminate two points 89 micrometers apart which would work out to about 287 pixels per inch.  Since the iPhone 4G display is comfortably higher than that measure at 326 pixels per inch, I’d find Apple’s claims stand up to what the human eye can perceive.

Great article about the pixel size and density of the new iPhone 4G, with some pleasantly nerdy microscope photography and technical explanation.
